Bengal Orange Bougainvillea

The Story

Plant Bio

Bougainvillea is a genus of scrambling evergreen climbers native to South America, characterised by long, arching stems armed with sharp thorns. The true flowers are small and tubular, but they are surrounded by large, papery, brightly coloured bracts that provide a prolonged visual display.

'Bengal Orange' is a cultivar distinguished by its variegated foliage of green and creamy-white, with new growth emerging in a coral-pink tone. The showy bracts are a pinkish-orange to vibrant sunset-orange, surrounding tiny, inconspicuous white or cream flowers.

Uses & Benefits:

Provides a long-lasting display of sunset-orange bracts contrasted against variegated green and cream foliage.

Functions as a physical barrier or security screen due to its sharp, woody thorns.

Attracts generalist native and introduced nectar-feeding insects, while providing structural habitat.

Planting

How to Grow

Select a planting site in full sun with well-draining loam, sandy loam, or clay-loam soil.
Ensure the soil pH is neutral to slightly acidic, ideally between 6.0 and 7.0.
Water moderately during the establishment phase, then reduce watering to allow the soil to dry out between applications.
Prune lightly after major flowering flushes in late winter or early spring to maintain shape and density.

Pro Tip

Avoid severe pruning into old, leafless wood, as these blind stems lack active buds and will fail to reshoot.

Keep It Thriving

Care Guide

Do

Plant in a position that receives full sun to ensure optimal bract development.
Improve soil drainage before planting to prevent waterlogged roots.
Apply a low-phosphorus, high-potassium fertiliser in spring to encourage flowering.

Don't

Do not over-fertilise with nitrogen, as this promotes excessive leaf growth at the expense of flowers.
Do not overwater or plant in heavy, poorly drained soils where root rot can develop.
Do not cut back radically into old, leafless woody stems.
